IMPROVED CAR-COUPLING.

Specification forming part of Letters Patent No. 79,982, dated July 14, 1868.

To uit whom, 'it muy concern:

Be it known that I, FREDERICK A. HULL, of Belvidere, in the county of Boone andState of llinois, have invented anew and useful Imprcvementin Ca1Gouplings 5 and I do hereby declare and make known that thet'ollowin g is a i'nll, clear, and exact description ot' the saine. reference being had to the accompanying drawings, and the letters and figures marked thereon, which forni part ot' this speciiication.

My said invention consists in constructing the draft-iron or drawheads of car-couplings of a tubular form, whereby the greatest degree of strength ot' the metal is obtained, and in combining therewith various appliances, producing a strong, simple, and safe coupling for railroad-ears, as hereinafter more fully described.

To'enablc those skilled in the art to understand how to construct and use my said invention, I will proceed to describe the saine with particularity, making reference in so doing to thc aforesaiddrawings, in which- Fgure 1 is aplan or top view ot my invention, and Fig. 2 is a horizontal longitudinal central section of the saine.

Similar letters of reference in the different iigures denote the same parts of my invention.

A represents the frame-work, of timber, in which the tubular draft-iron B'issecured, and whereby it is attached to the car, as hereinafter explained. Through theA said draft-iron pass two metallic bars, D and E, whose ends rest in slots a in the frame A, as seen in Fig. 2, said tube B resting upon a suitable support at the front end of the frame A,as seen at H. Within said tubular draft-iron, and between the bars l) E, is arranged a spiral spring, S, or its equivalent, so that when the'draft is applied to draw the car it comes upon 'the rear end ot the spring S, land when the ears are backed or run together the concussion cornes upon the front end otl the spring S, the slots aforesaid being arranged with respect tothe bars D and E to operate in that manner.

C represen ts a bar passing through the front end of the drattiron, one end of which is provided with links e, the opposite end ot' which links may be slipped over the corresponding end of the corresponding bar in the opposite draft-iron, when e it may be secured by means ot' pins d, as shown,l being the main link, and b the ordinary coupling-pin. By this arrangement when the coupling pin or link is broken or 10st one or both ot' the auxiliary links may be used, and it' used in conjunction with thc principal link and pin, should either be broken while the train is in motion, the others will prevent the separation ot' the train, as desired.

Having described the construction and operation ot' my invention, I will proceed to specify what [claim and desire to secure by Letters Patent:

The combination of the tubular draft-iron B, the bars D E, the spring S, and the link l and pin b, arranged and operating substantially as specified and shown.

F. A. HULL.
